If any question isn't in the questions.txt file or any answer isn't in the answers.txt file, or the answer is wrong, then the files are wrong, the program is still 100% correct. It can always pass the Turing test given correct data.

Okay, let me revise that statement to this: The program never fails on its own merits, it only fails as a result of erroneous input. But the same can be said of any program for which there exists a distinction between valid and invalid input - garbage in, garbage out.

@helios
It would if the data were correct. I know you say that the data can't ever be correct, but that's not a failure of the program, that's a failure of god to provide a universe where a set of all possible data can exist.
